Description

Technical Field

[0001] The present application relates to the technical field of board cutting, and in particular to a reversing mechanism for processing log boards. Background Art

[0002] The log is cylindrical, and the first step of processing is to cut off the outer circle to form a rectangular cross-section structure. It is usually cut by manual pushing. After the single-sided cutting is completed, it needs to be turned 90° and cut again until all the faces are cut into planes before the formal processing can be carried out;

[0003] Since the logs are heavy, they need to be turned over manually when processing different sides, which is labor-intensive and may cause hands to be caught during turning, which is unsafe.

[0004] In order to solve the above problems, the present application proposes a log board processing reversal mechanism. Utility Model Content

[0006] The present application provides a log board processing reversal mechanism, comprising a cutting table, on which a cutting machine is installed, and on which a flipping mechanism, a buffer mechanism, and a positioning mechanism are respectively installed, wherein the buffer mechanism is located between the flipping mechanism and the positioning mechanism, the flipping mechanism flips the cut logs, the buffer mechanism buffers the flipped logs, and the positioning mechanism positions the flipped logs.

[0007] Preferably, the flipping mechanism includes a right-angle flipping frame hinged on the cutting table, an avoidance frame fixed at the lower end of the right-angle flipping frame, and a flipping cylinder hinged on the avoidance frame. The right-angle flipping frame is located at the lower end of the cutting path in a reset state and is flush with the cutting table. The flipping mechanism also includes a support frame fixed to the bottom of the cutting table. The flipping cylinder is hinged on the support frame. The flipping cylinder pushes the right-angle flipping frame and the avoidance frame to flip along a rotating shaft connected to the cutting table.

[0008] Preferably, the buffer mechanism includes a buffer seat arranged in the cutting table and an energy absorbing block located at the upper end of the buffer seat, a movable rod fixed at the lower end of the energy absorbing block and passing through the buffer seat, and an energy absorbing spring arranged between the energy absorbing block and the buffer seat.

[0009] Preferably, a limiting block is fixed to the portion of the bottom of the movable rod that passes through the buffer seat, and the energy absorbing block is higher than the upper surface of the cutting table through an energy absorbing spring.

[0010] Preferably, the buffer mechanism further comprises a pressing plate, which is fixed to the movable end of the positioning mechanism and cooperates with the energy absorbing block. The pressing plate squeezes the energy absorbing block and presses it into the cutting table.

[0011] Preferably, the positioning mechanism includes a fixing frame fixed on the cutting table and a positioning plate arranged at the front end of the fixing frame, a positioning cylinder fixed on the fixing frame and having its output end fixed to the positioning plate, and a guide rod fixed on the positioning plate and sliding through the fixing frame.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] Firstly, the flipping mechanism can flip the log after one side is cut, switching the processing side without manual operation, effectively reducing the workload, and at the same time, it will not cause hand pinching, making it safer; secondly, the positioning mechanism can not only block the log during flipping, but also limit the log during cutting, ensuring reliable flipping and cutting; finally, the buffer mechanism has a buffering effect to avoid huge noise after the board is flipped.

[0020] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0021] Reference Figure 1 - Figure 2A log board processing reversing mechanism comprises a cutting table 1, on which a cutting machine 2 is installed, and on which a turning mechanism 3, a buffer mechanism 4 and a positioning mechanism 5 are respectively installed, wherein the buffer mechanism 4 is located between the turning mechanism 3 and the positioning mechanism 5, the turning mechanism 3 turns the cut logs, the buffer mechanism 4 buffers the turned logs, and the positioning mechanism 5 positions the turned logs.

[0022] Reference Figure 3 The turning mechanism 3 includes a right-angle turning frame 31 hinged on the cutting table 1, an avoidance frame 32 fixed at the lower end of the right-angle turning frame 31, and a turning cylinder 33 hinged on the avoidance frame 32. The right-angle turning frame 31 is located at the lower end of the cutting path in the reset state and is flush with the cutting table 1; the turning mechanism 3 also includes a support frame 34 fixed at the bottom of the cutting table 1, and the turning cylinder 33 is hinged on the support frame 34. The turning cylinder 33 pushes the right-angle turning frame 31 and the avoidance frame 32 to turn along the rotating shaft connected to the cutting table 1. The turning mechanism 3 can turn over after cutting one side of the log and switch the processing side. No manual operation is required, which effectively reduces the work intensity. At the same time, there will be no hand pinching phenomenon, which is safer.

[0023] Reference Figure 4-Figure 5 The buffer mechanism 4 includes a buffer seat 41 arranged in the cutting table 1 and an energy absorbing block 42 located at the upper end of the buffer seat 41, a movable rod 43 fixed at the lower end of the energy absorbing block 42 and passing through the buffer seat 41, and an energy absorbing spring 45 arranged between the energy absorbing block 42 and the buffer seat 41; a limited block 44 is fixed to the part of the movable rod 43 that passes through the buffer seat 41 at the bottom, and the energy absorbing block 42 is higher than the upper surface of the cutting table 1 through the energy absorbing spring 45. The buffer mechanism 4 has a buffering effect to avoid huge noise after the plate is flipped.

[0024] Reference Figure 4 - Figure 5 The buffer mechanism 4 also includes a pressing plate 46, which is fixed to the movable end of the positioning mechanism 5, and the pressing plate 46 also cooperates with the energy absorbing block 42. The pressing plate 46 squeezes the energy absorbing block 42 and presses it into the interior of the cutting table 1. The cooperation between the pressing plate 46 and the energy absorbing block 42 is used to avoid the buffer mechanism 4 when the positioning mechanism 5 is in the cutting state, ensuring buffering while not affecting reliable cutting.

[0025] Reference Figure 5 The positioning mechanism 5 includes a fixing frame 51 fixed on the cutting table 1 and a positioning plate 52 arranged at the front end of the fixing frame 51, a positioning cylinder 53 fixed on the fixing frame 51 and having an output end fixed to the positioning plate 52, and a guide rod 54 fixed on the positioning plate 52 and sliding through the fixing frame 51. The positioning mechanism 5 can not only play a blocking role during flipping, but also play a limiting role during cutting, thereby ensuring reliable flipping and cutting.

[0026] Working principle: Place the log on the cutting table 1 between the cutting machine 2 and the positioning mechanism 5. The positioning cylinder 53 drives the positioning plate 52 forward to move the log to the desired cutting position. At this time, the pressing plate 46 presses the energy absorbing block 42 downward by chamfering, and the energy absorbing spring 45 is compressed, turning on the cutting machine 2 and pushing the log to cut.

[0027] After one side cutting is completed, the positioning cylinder 53 drives the positioning plate 52 to retreat, leaving enough turning space. When the positioning mechanism 5 retreats, the pressure plate 46 disengages from the squeeze on the energy absorbing block 42, and the energy absorbing spring 45 pushes the energy absorbing block 42 upward to the upper end of the cutting table 1. The flipping cylinder 33 drives the avoidance frame 32 and the right-angle flipping frame 31 to flip. When the right-angle flipping frame 31 flips upward, the log at the upper end is flipped. The log is flipped on the energy absorbing block 42 and buffered under the action of the energy absorbing spring 45. The flipping cylinder 33 drives the right-angle flipping frame 31 and the avoidance frame 32 to reset. The positioning cylinder 53 drives the positioning plate 52 to push the flipped log to the cutting position, and the cutting process is performed again.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
